我是Ruby on Rails的新手,我一直在关注如何使用Devise,Haml和Simple_Form创建论坛应用程序的Mackenzie Child的教程。我在Windows 10 O.S.上使用Aptana Studio 3作为IDE。我正在使用Ruby 2.2.0和Rails版本4.2.5.1。Rails宝石和服务器的持续问题
我有两个问题:
1)我无法摧毁它创建后的后(如麦肯锡说明在大约时间为17:30)。
经过Google搜索,我发现这是因为我从application.html.erb
中删除了JavaScript和StyleSheet脚本。我删除了这些代码行,因为我无法查看本地服务器上的任何Rails应用程序。这导致我到我的第二个问题
2)我把代码行回到application.html.erb
文件夹,我回到无法查看我的本地网络上的应用程序,并收到以下列出的错误代码。
同样,谷歌的搜索发现coffee-script-source
,1.10.0
不适用于windows,这就是为什么我收到错误。我被建议回滚到1.8.0
。但是,我无法回滚到早期版本。我尝试在我的GemFile中输入正确的CoffeeScript版本,并尝试gem install
'coffee-script-source','1.8.0',但是我的电脑拒绝更新它。相反,我在终端中收到此错误。
>You have requested: coffee-script-source = 1.8.0
>The bundle currently has coffee-script-source locked at 1.10.0.
>Try running 'bundle update coffee-script-source'
>If you are updating multiple gems in your Gemfile at once,
>try passing them all to 'bundle update'"*
无论如何,这是Google停止帮助的地方。如果有人能帮助我解决这个问题,我将不胜感激!
